In addition, the description regarding the handle 80 is demonstrated on the basis of the state which pulled the handle 80 back.

  Further, a thick plate portion 84 is formed on the upper surface of the grip portion 83, and the thick plate portion 84 has an upper end front edge portion on the shaft portion 81 side from the upper end front edge portion (the guide column 23 of the slider body 20). A pair of left and right engaging projections 85 extending to the side) are formed. The engaging projection 85 snap-engages with the front edge portion of the upper blade 21 when the handle 80 is tilted to the guide column 23 side (front side) (see FIGS. 7 and 8). The plan view shape of the thick plate portion 84 is the same as that of the grip portion 83.

  Further, as shown in FIG. 8, the gap dimension T1 between the leg portion 82 of the handle 80 and the engaging projection 85 is set to be larger than the plate thickness dimension T2 of the upper blade 21 (T1> T2). Preferably it is. For this reason, the left and right engaging protrusions 85 can be engaged with the front edge portion of the upper blade 21.

  The clearance dimension T1 between the leg portion 82 of the pull handle 80 and the engaging projection 85 may be set equal to the plate thickness dimension T2 of the upper blade 21 (T1 = T2). In this case, the pulling of the handle 80 when the left and right engaging protrusions 85 are engaged with the front edge portion of the upper blade 21 is further prevented. When the handle 80 is formed of a material that can be elastically deformed (plastic, rubber, urethane, or the like), the gap dimension T1 between the leg portion 82 of the handle 80 and the engaging protrusion 85 is determined by the upper wing plate 21. It may be set smaller than the plate thickness dimension T2 (T1 <T2). In this case, when the left and right engaging projections 85 are engaged with the front edge portion of the upper wing plate 21, the upper wing plate 21 is press-fitted between the leg portion 82 and the engaging projection 85 of the handle 80 (upper wing The plate 21 pushes the leg 82 of the handle 80 and the engaging projection 85 up and down, and the upper blade 21 is sandwiched between the leg 82 and the engaging projection 85). .

  As shown in FIG. 4, the left and right side surfaces 86 of the pull handle 80 are formed so as to be inclined so that the width dimension W <b> 1 of the pull handle 80 gradually increases from the shaft portion 81 toward the grip portion 83. Thereby, since the width dimension of the grip part 83 can be enlarged, the width dimension W2 of the engaging protrusion 85 can be enlarged. For this reason, the engaging force of the engaging protrusion 85 can be increased. Further, by increasing the width dimension W2 of the engaging protrusion 85, it is possible to form a flat surface or a curved surface at the front end (front end) of the engaging protrusion 85. The touch of 85 can be softened.

  Further, the width dimension W3 of the recess 87 formed between the left and right engaging protrusions 85 is set to a size that fits with the front end portion of the guide column 23 of the slider body 20 (see FIG. 7). Accordingly, since the front end portion of the guide column 23 is fitted into the recess 87 when the handle is engaged, when the handle 80 is hung from side to side, the engagement protrusion 85 and the guide column 23 come into contact with each other. Directional movement can be restricted.

  Further, projecting pieces 82a projecting outward in the width direction are formed at the ends of the left and right leg portions 82 on the shaft portion 81 side. Thereby, when the handle 80 rotates with respect to the slider body 20, the projecting piece 82a comes into contact with the upper wing plate 21, and thus the swing of the handle 80 in the width direction during the handle operation can be prevented. The left and right engaging protrusions 85 can be easily engaged with the front edge of the upper blade 21. The projecting piece 82a is formed in a substantially trapezoidal shape having a flat surface that is flush with the end surface of the handle 80 on the shaft 81 side.

  As shown in FIG. 2, a space SP is formed between the engaging protrusion 85 of the handle 80 and the upper surface of the rear portion of the cover member 50 in a state where the handle 80 is tilted backward. . Thereby, since it becomes easy to grasp the handle 80 with a finger, the operativity of the slider 10 can be improved.

  As described above, according to the slide fastener slider 10 of the present embodiment, the grip portion 83 of the handle 80 engages with the front edge portion of the upper blade 21 when the handle 80 is tilted to the guide column 23 side. Since the pair of left and right engaging protrusions 85 are provided, the pair of left and right engaging protrusions 85 are engaged with the front edge portion of the upper wing plate 21, thereby preventing the handle 80 from wobbling. And the design change of the slider body 20 is unnecessary.

  Further, according to the slide fastener slider 10 of the present embodiment, the gap dimension T1 between the leg portion 82 of the handle 80 and the engaging protrusion 85 is set to be larger than the plate thickness dimension T2 of the upper blade 21. Therefore, the left and right engaging projections 85 can be easily engaged with the front edge portion of the upper blade 21.

  Further, according to the slide fastener slider 10 of the present embodiment, the left and right side surfaces 86 of the handle 80 are formed so as to be inclined so that the width dimension W1 of the handle 80 gradually increases from the shaft portion 81 toward the grip portion 83. Therefore, the width dimension of the grip portion 83 can be increased. Thereby, since the width dimension W2 of the engaging protrusion 85 can be increased, the engaging force of the engaging protrusion 85 can be increased, and the feel of the engaging protrusion 85 during the pulling operation can be softened. be able to.

  Further, according to the slide fastener slider 10 of the present embodiment, the width dimension W3 of the recess 87 formed between the left and right engaging protrusions 85 is large enough to fit with the front end portion of the guide column 23 of the slider body 20. Therefore, when the handle is engaged, the front end portion of the guide post 23 is fitted into the recess 87, and the movement of the handle 80 in the width direction can be restricted.

  Further, according to the slide fastener slider 10 of the present embodiment, the projecting pieces 82a projecting outward in the width direction are formed at the end portions on the shaft portion 81 side of the left and right leg portions 82, respectively. The swinging of the handle 80 in the width direction can be prevented. For this reason, the left and right engaging protrusions 85 can be easily engaged with the front edge portion of the upper blade 21.

  As a first modification of the present embodiment, as shown in FIGS. 8 and 9, the pair of left and right engaging protrusions 85 may be formed to extend from the pair of left and right legs 82 of the pull handle 80. Good.

  Further, as a second modification of the present embodiment, a synthetic resin coating may be formed on the surface of the shaft portion 81 of the handle 80, or a synthetic resin tape may be wound around the surface of the shaft portion 81. Good. In this case, it is possible to prevent contact noise between the shaft portion 81 of the handle 80 and the lock member 40 during slider vibration or the like.
